I'm bumping this thread.

I've got a similar timing at NRT. In at 5:00 PM out at 2:00PM the next day. I've never been to Japan. If I only have that amount of time, I assume after reading this thread I won't be able to get into Tokyo, and i'll have to stick to Narita? Should I try and do everything possible to extend my stay by another night? What are the top 3 things that are must sees if I hit tokyo? Also appreciate a hotel suggestion (or should I try and go all night?)
